The canonical division of the Vedas is fourfold ('''') viz., •
Rigveda (RV) •
Yajurveda (YV, with the main division
TS vs.
VS) •
Samaveda (SV) •
Atharvaveda (AV) Of these, the first three were the principal original division, also called "''''"; that is, "the triple science" of reciting hymns (Rigveda), performing sacrifices (Yajurveda), and chanting songs (Samaveda). The Rig Veda most likely was composed between 1500 BCE and 1200 BCE. Witzel notes that it is the Vedic period itself, where incipient lists divide the Vedic texts into three (trayī) or four branches: Rig, Yajur, Sama and Atharva. Only one version of the Rigveda is known to have survived into the modern era. The texts of the Upanishads discuss ideas akin to the heterodox ś
ramana-traditions.
Rigveda The
Rigveda Samhita is the oldest extant
Indic text. It is a collection of 1,028
Vedic Sanskrit hymns and 10,600 verses in all, organised into ten books (Sanskrit:
mandalas). The hymns are dedicated to
Rigvedic deities. The books were composed by poets from different priestly groups over a period of several centuries between 1500 and 1200 BCE, (the early
Vedic period) in the
Punjab (
Sapta Sindhu) region of the northwest
Indian subcontinent. According to Michael Witzel, the initial codification of the
Rigveda took place at the end of the Rigvedic period at , in the early
Kuru kingdom. The Rigveda is structured based on clear principles. The Veda begins with a small book addressed to Agni, Indra,
Soma and other gods, all arranged according to decreasing total number of hymns in each deity collection; for each deity series, the hymns progress from longer to shorter ones, but the number of hymns per book increases. Finally, the meter too is systematically arranged from jagati and tristubh to anustubh and gayatri as the text progresses. The rituals became increasingly complex over time, and the king's association with them strengthened both the position of the Brahmans and the kings. The
Rajasuya rituals, performed with the coronation of a king, "set in motion [...] cyclical regenerations of the universe." In terms of substance, the nature of hymns shift from praise of deities in early books to
Nasadiya Sukta with questions such as, "what is the origin of the universe?, do even gods know the answer?", and other metaphysical issues in its hymns. There are similarities between the mythology, rituals and linguistics in Rigveda and those found in ancient central Asia, Iranian and Hindukush (Afghanistan) regions.
Yajurveda The
Yajurveda Samhita consists of prose mantras. It is a compilation of ritual offering formulas that were said by a priest while an individual performed ritual actions such as those before the
yajna fire. The core text of the Yajurveda falls within the classical Mantra period of
Vedic Sanskrit at the end of the 2nd millennium BCE – younger than the
Rigveda, and roughly contemporary with the
Atharvaveda, the Rigvedic
Khilani, and the Samaveda|. Witzel dates the Yajurveda
hymns to the early Indian
Iron Age, after c. 1200 and before 800 BCE corresponding to the early
Kuru kingdom. The earliest and most ancient layer of Yajurveda Samhita includes about 1,875 verses, that are distinct yet borrow and build upon the foundation of verses in
Rigveda. Unlike the Samaveda which is almost entirely based on Rigveda mantras and structured as songs, the Yajurveda Samhitas are in prose, and they are different from earlier Vedic texts linguistically. The Yajurveda has been the primary source of information about sacrifices during Vedic times and associated rituals. There are two major groups of texts in this Veda: the "Black" (
Krishna) and the "White" (
Shukla). The term "black" implies "the un-arranged, motley collection" of verses in Yajurveda, in contrast to the "white" (well arranged) Yajurveda. The White Yajurveda separates the Samhita from its Brahmana (the
Shatapatha Brahmana), the Black Yajurveda intersperses the Samhita with Brahmana commentary. Of the Black Yajurveda, texts from four major schools have survived (Maitrayani, Katha, Kapisthala-Katha, Taittiriya), while of the White Yajurveda, two (Kanva and Madhyandina). The youngest layer of Yajurveda text is not related to rituals nor sacrifice, it includes the largest collection of primary Upanishads, influential to various schools of
Hindu philosophy.
Samaveda The
Samaveda Samhita consists of 1549 stanzas, taken almost entirely (except for 75 mantras) from the Rigveda. While its earliest parts are believed to date from as early as the Rigvedic period, the existing compilation dates from the post-Rigvedic Mantra period of
Vedic Sanskrit, between and 1000 BCE or "slightly later", roughly contemporary with the
Atharvaveda and the
Yajurveda. Including repetitions, there are a total of 1875 verses numbered in the Samaveda recension translated by Griffith. Two major recensions have survived, the
Kauthuma/Ranayaniya and the Jaiminiya. Its purpose was liturgical, and they were the repertoire of the
'''' or "singer" priests.
Atharvaveda The
Artharvaveda Samhita is the text belonging to the
Atharvan and
Angirasa poets. It has about 760 hymns, and about 160 of the hymns are in common with the Rigveda. Most of the verses are metrical, but some sections are in prose. Two different versions of the text – the and the – have survived into the modern times. The Atharvaveda was not considered as a Veda in the Vedic era, and was accepted as a Veda in late 1st millennium BCE. It was compiled last, probably around 900 BCE, although some of its material may go back to the time of the Rigveda, or earlier. The Atharvaveda is sometimes called the "Veda of magical formulas", an epithet declared to be incorrect by other scholars. The
Samhita layer of the text likely represents a developing 2nd millennium BCE tradition of
magico-religious rites to address superstitious anxiety, spells to remove maladies believed to be caused by demons, and herbs- and nature-derived potions as medicine. The text, states Kenneth Zysk, is one of oldest surviving record of the evolutionary practices in religious medicine and reveals the "earliest forms of folk healing of Indo-European antiquity". Many books of the Atharvaveda Samhita are dedicated to rituals without magic, such as to philosophical speculations and to
theosophy.
Embedded Vedic texts Brahmanas The Brahmanas are commentaries, explanation of proper methods and meaning of Vedic Samhita rituals in the four Vedas. They also incorporate myths, legends and in some cases philosophy. Each regional Vedic
shakha (school) has its own operating manual-like Brahmana text, most of which have been lost. A total of 19 Brahmana texts have survived into modern times: two associated with the
Rigveda, six with the
Yajurveda, ten with the
Samaveda and one with the
Atharvaveda. The oldest dated to about 900 BCE, while the youngest Brahmanas (such as the
Shatapatha Brahmana), were complete by about 700 BCE. The first hymn is a recitation that accompanies offering a
Yajna oblation to
Agni (fire) on the occasion of a marriage, and the hymn prays for prosperity of the couple getting married. The second hymn wishes for their long life, kind relatives, and a numerous progeny. The Samhitas and Brahmanas describe daily rituals and are generally meant for the
Brahmacharya and
Gr̥hastha stages of the
Chaturashrama system, while the Aranyakas and
Upanishads are meant for the
Vānaprastha and
Sannyasa stages, respectively.
Aranyakas and Upanishads The Aranyakas layer of the Vedas include rituals, discussion of symbolic meta-rituals, as well as philosophical speculations. Aranyakas, however, neither are homogeneous in content nor in structure. The Upanishads reflect the last composed layer of texts in the Vedas. They are commonly referred to as
Vedānta, variously interpreted to mean either the "last chapters, parts of the Vedas" or "the object, the highest purpose of the Veda". The central concern of the Upanishads are the connections "between parts of the human organism and cosmic realities". The Upanishads intend to create a hierarchy of connected and dependent realities, evoking a sense of unity of "the separate elements of the world and of human experience [compressing] them into a single form." The concepts of
Brahman, the Ultimate Reality from which everything arises, and
Ātman, the essence of the individual, are central ideas in the Upanishads, and knowing the correspondence between Ātman and Brahman as "the fundamental principle which shapes the world" permits the creation of an integrative vision of the whole. and of the Vedic corpus, they alone are widely known, and the central ideas of the Upanishads have influenced the diverse traditions of Hinduism.
Aranyakas are sometimes identified as
karma-kanda (ritualistic section), while the
Upanishads are identified as
jnana-kanda (spirituality section). In an alternate classification, the early part of Vedas are called
Samhitas and the commentary are called the
Brahmanas which together are identified as the ceremonial
karma-kanda, while
Aranyakas and
Upanishads are referred to as the
jnana-kanda. ==Post-Vedic literature==
